Question

In my project (Silverlight5 with MVVM), i need to hide the Grid using button click event. here the button also located in the grid. Is there anyway to hide this grid..?

Answer 1

Your viewmodel should contain property (for example, IsGridVisible):

public bool IsGridVisible
{
   get {return _isGridVisible;}
   set {
          _isGridVisible = value;
          OnPropertyChanged("IsGridVisible");
       }
}

Then, you can bind Grid.Visibility to your IsGridVisible property, thought BoolToVisibilityConverter.

And then, you can simply switch state in your button`s command handler.
